The first FORTRAN (which stands for Formula Translation) compiler was developed
in 1957 at IBM. In 1966 the American Standards Association (later the America
National Standards Institute, ANSI) released the first standard version of FORTRAN,
which later became known as FORTRAN 66. The standard aimed at providing a
standardised, portable language, which could easily be transferred from one computer
system to the other. In 1977, a revised version of FORTRAN, FORTRAN 77, was
completed (the standard was published in 1978). The next version is Fortran 90, which is
a major advance over FORTRAN 77. It contains many new features; however, it also
contains all of FORTRAN 77. Thus, a standard-conforming FORTRAN 77 program is
also a standard-conforming Fortran 90 program. Some of FORTRAN 77’s features were
identified as “obsolescent”, but they were not deleted. Obsolescent features are
candidates for deletion in the next standard, and should thus be avoided. The latest
standard is Fortran 95. Fortran 95 contains only minor changes to Fortran 90; however, a
few of the obsolescent features identified in Fortran 90 were deleted…
